I suspect Manuel is confusing PHP's built-in mail() function which does spawn a new sendmail process for email function call with sendmail itself, which does not -- at least not unless you really work hard at it. As to not configuring sendmail to queue/store/send-later, I guess that might still be the default, but it's a pretty stupid setup for mass email. -- Some people have a "gift" link here.
